Public concerns about the health risks of synthetic antioxidants have prompted the meat industry to look for natural alternatives rich in phenols with strong antioxidant properties. This study investigates the use of blackcurrant (BCP), lingonberry (LP), and sour cherry (SCP) powders as natural substitutes for synthetic nitrites in reformulating two clean-label salami types, smoked and cooked and smoked and scalded, with a focus on their effects on oxidative stability during processing and refrigerated storage (4 °C). Nitrite-free formulations were prepared with each fruit powder at three inclusion levels to provide total phenolic contents of 90, 200, and 300 mg gallic acid equivalents (GAE)/kg of processed meat. A nitrite-containing control (90 mg/kg) and an additive-free control were included for comparison. The phytochemical profiles of powders were characterized by total phenolic, flavonoid, monomeric anthocyanin contents, and L-ascorbic acid levels. Antioxidant activity was assessed via 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and ferric reducing antioxidant power (FRAP) assays. Salami samples were analyzed for proximate composition, and lipid oxidation was monitored at 0, 15, and 30 days of storage using peroxide value, inhibition of oxidation, p-anisidine value, TOTOX, and thiobarbituric acid value. Fruit powders demonstrated dose- and type-dependent inhibition of primary and secondary lipid oxidation, enhancing oxidative stability during processing and storage. After 30 days of storage, oxidation markers in fruit-enriched salami remained below recommended thresholds, confirming effective control of lipid oxidation. The inhibitory potential followed the order BCP > LP > SCP, consistent with antioxidant profiles as reflected by DPPH and FRAP values. BCP at 300 mg GAE/kg showed a stronger lipid oxidation inhibition than sodium nitrite. Promising improvements in lipid oxidation resistance were also observed with LP at 300 mg GAE/kg and BCP at 200 mg GAE/kg. These findings highlight the potential of fruit-derived antioxidants to support the development of more sustainable, value-added meat products without compromising quality. Full article

Meat plays a key role in human nutrition, providing protein of high digestibility and essential micronutrients. However, according to the FAO and WHO, excessive consumption of red and processed meats may increase health risks due to their content of saturated fats, sodium, and E-number additives. For this reason, recent research has focused on the nutritional reformulation of meat products to develop functional and health-promoting alternatives that meet consumer expectations and respond to market trends for healthier and more sustainable foods. However, the addition or elimination of traditional ingredients in meat products leads to problems such as changes in texture, color, or sensory acceptability that must be solved. This review will focus on current reformulation strategies in the meat industry, including the reduction or replacement of animal fat with vegetable oils using technologies such as microencapsulation, or the elaboration of 3D gels using organogelants and hydrocolloids; the replacement of the umami flavor of salt with extracts from seafoods and mushrooms; the replacement of E-number additives with antioxidant and preservative extracts from plants and herbs; and the incorporation of dietary fiber through fruit peels and vegetable by-products.

The limited number of additives in plant-based burgers is related to clean label consumer perception, which influences purchase intention. Starch is typically combined with other texturing agents to replicate the texture and mouthfeel of meat burgers. It is necessary to reformulate these products following consumers’ trends, who prefer healthier products with fewer additives. Two hydrocolloids with significant commercial application and different functionality were evaluated: methylcellulose (M) or sodium alginate (SA). Four formulations were developed, two containing starch (M+S and SA+S) and two without starch (M and SA). The alginate burgers provided samples with high water retention capacity and a cohesive and adhesive texture, superior to the samples with methylcellulose, without the need to add starch, due to their stabilizing, thickening, and gelling properties derived from their “egg-crate” structure when gelled. Furthermore, sensory analysis indicated that the sodium alginate burgers had a softer and creamier texture. In contrast, starch removal in the methylcellulose burgers enhanced their appearance due to gel transparency and desirable textural properties, akin to those of meat. These results promote using a 3 g/100 g methylcellulose solution as the sole binding agent in soybean burgers to achieve a product with reduced additives. Full article

This study reviews the feasibility of using cultivated mushrooms in the development of salt-reduced meat products. For this purpose, it is important to know the role of salt in meat products in order to develop viable strategies for its substitution. In addition, mushroom types and properties (composition, nutritional value, umami content, etc.) and examples of successful application as salt substitutes in meat products are addressed. Salt has important roles in meat product processing, mainly affecting its technological, antimicrobial, and sensory properties. Therefore, the different strategies that have been studied (meat product reformulation and technological advances) with the aim of reducing its content have to address these effects. The application of mushrooms as a salt substitute shows several advantages mainly related to the fact that mushrooms are a natural ingredient with a very healthy nutritional composition (rich in protein and dietary fiber but low in fat and sodium) and, from an economic and sustainable cultivation perspective, aligns well with current trends in food production and consumption. Salt substitutions of 50% have been achieved, mainly in fresh meat products (hamburgers) and heat-treated meat products (sausages, pâté, roast meat, etc.), with minimal physicochemical and sensory modifications of the final product. The meat industry could benefit from incorporating cultivated mushrooms as a salt-reducing ingredient, especially in the development of reduced salt meat products with a quality comparable to or superior to traditional products. The optimization of processes for their integration in the formulation of meat products should be the trend to ensure their viability. Full article

Background: To help consumers make healthier choices, the US Food and Drug Administration (FDA) has been charged with developing a front-of-package label (FOPL) to appear on US packaged foods and beverages. One option being explored is the use of “high-in” FOPLs for added sugar, sodium, and saturated fat using a threshold of ≥20% of the recommended daily value (%DV) per portion/serving size to define “high-in”. While research has addressed what FOPL designs are most effective at visually communicating “high-in”, less attention has been paid to the nutrient profile model (NPM) used to decide which products should receive these labels. In addition, several established regional NPMs already exist that identify products that are high in nutrients of concern, but it is unclear how these compare to the FDA’s %DV approach. Methods: We used a dataset of 51,809 US products from Mintel’s Global New Products Database to examine how the FDA’s current definition of “high-in” compares to three established regional NPMs: the Canadian NPM, the Pan American Health Organization (PAHO) NPM, and Chile’s NPM. Results: Overall agreement between the four NPMs was 51% for foods and 72% for beverages, with highest agreement in categories such as sweetened sodas (87%), and lowest agreement in categories such as bread (14%) and salty snacks (29%). The Canadian NPM showed the highest agreement to the FDA “high-in” criteria while the Chilean and PAHO models had lower agreement. For many food categories, the FDA’s definition of “high-in” would require the fewest products to carry a “high-in” label. This issue was particularly pronounced in categories that tend to be served in small portions (e.g., salty snacks, bars), but disappeared or reversed for categories that are served in larger portions (e.g., frozen and non-frozen main dishes). Conclusions: The NPM chosen has important policy implications for an FOPL system’s ability to identify unhealthy foods and incentivize companies to reformulate products. Based on these results, the FDA should consider using a stronger NPM similar to those used elsewhere in the Americas region when deciding the final thresholds for “high-in” for US packaged foods and beverages.

Front-of-pack labeling (FOPL) may represent an important instrument for the food industry in the promotion of food product reformulation. The present cross-sectional study used salt reduction in packaged breads as a case study, aiming to investigate whether two different types of FOPL (i.e., Nutri-Score (NS) and NutrInform battery (NIB)) can capture food reformulation and thus be effective tools for encouraging reformulation. The Nutri-Score and NIB were calculated by consulting the nutritional declarations and ingredient lists of 527 packaged breads currently sold in Italy before and after applying three different theoretical reformulation strategies: (i) a 25% salt decrease from the current median salt content in bread; (ii) a reduction of up to 0.825 g/100 g of salt, corresponding to the sodium benchmark of 330 mg/100 g set by the World Health Organization (WHO); and (iii) the minimum salt reduction needed to improve the NS by one grade. The results show that only ~44% of breads had improved NSs when the sodium was lowered to reach the WHO benchmark or when salt was reduced by 25%, whereas large variability was observed in the minimum salt reduction needed to improve the NS. Regarding the NIB, the battery for salt improved when both strategies of reformulation were applied. FOPL is not always effective in capturing food reformulation in terms of salt reduction, possibly discouraging the efforts of food companies to improve the nutritional quality of foods. Full article

Background/Objectives: Low quality diets are a risk factor for non-communicable diseases; therefore, improving diet quality is a public health and policy priority in the UK and elsewhere. Reformulating food/beverage products to make them healthier may be an effective approach. Evidence suggests that fiscal interventions, notably taxes/levies on soft drinks, can lead to reformulation but the evidence for voluntary or mandated non-fiscal interventions is less clear. We aimed to review and synthesise contemporary evidence to determine whether non-fiscal policies/interventions result in the reformulation of food/beverage products Methods: In April 2023, we systematically searched ten international academic and nine grey literature databases. We included real-world study designs, all nutrients, in- and out-of-home sectors, and studies published from 2013, to ensure policy relevancy. We excluded modelling studies. Using the Synthesis Without Meta-Analysis method we conducted vote counting of studies based on the direction of effect and narrative synthesis by intervention type. Risk of bias was assessed using a tool developed by the EPPI-Centre and quality was assessed using GRADE. Results: We included 77 real-world studies from 19 countries, reporting 100 non-fiscal policies/interventions. Most commonly, these were reduction targets (n = 44), front-of-pack labels (n = 23), and advertising standards (n = 9). Most interventions were voluntary (n = 67), compared to mandatory (n = 33), and focused on the in-home sector (n = 63). The vote counting results showed non-fiscal policies/interventions overall led to improvements in reformulation in 60/63 studies with a valid direction of effect (95%, 95% CI 0.869, 0.984, p < 0.001). Mandatory implementations were more successful than voluntary implementations with 15/15 showing an improvement (100%, 95% CI 0.796, 1], p < 0.001), compared 40/43 showing an improvement (93%, 95% CI 0.814, 0.976, p < 0.001). Most of the studies were of low quality, due to the observational nature of the studies. Sodium was the most commonly targeted nutrient (n = 56) and was found to be reformulated in most studies. Causation is difficult to establish from real-world studies, but evidence suggests that regulatory and multi-component strategies may be effective at driving reformulation. Conclusions: Non-fiscal policies/interventions can play an important role in driving reformulation, alongside fiscal measures.

Numerous nutrient profiling models (NPMs) exist worldwide, but Japan lacks an official NPM. Using the Australian and New Zealand Health Star Rating (HSR) as a reference, “Processed Foods in Japan version 1.0” (NPM-PFJ (1.0)) was developed to fit Japanese food culture and policies. In total, 668 processed foods from the Standard Tables of Food Composition in Japan were analyzed, excluding seasonings/spices, fats/oils, alcoholic beverages, and infant food. The NPM-PFJ (1.0) scoring algorithm was adapted from HSR, with revised reference values for energy, saturated fat, total sugars, sodium, protein, and dietary fiber in alignment with Japanese standards. Reference values for fruits, vegetables, nuts, and legumes (fvnl) remained unchanged. Median scores were 4.5 for HSR and 5.0 for NPM-PFJ (1.0), showing high correlation (r = 0.939, p < 0.01). Thereafter, food categories familiar and meaningful in Japan were defined based on a hierarchical cluster analysis of scoring patterns, creating six categories with distinct characteristics. Finally, the rating algorithm for NPM-PFJ (1.0) was created using each group’s score distribution (10th percentile). The NPM-PFJ (1.0) was developed through a fully transparent and evidence-based process and is expected to facilitate the reformulation of food products by food industries and help consumers easily access healthier processed foods. This model marks a significant step forward in developing an NPM tailored to Japanese food culture and health policies, with the potential to enhance public health. Full article

To address the rising incidence of non-communicable diseases (NCDs) and promote healthier eating habits, Japan requires a culturally tailored Nutrient Profile Model. This study aimed to develop a Nutrient Profile Model for Dishes in Japan version 1.0 (NPM-DJ (1.0)) that corresponds to the nutritional issues and food culture in Japan. The aim of the NPM-DJ (1.0) was to promote the health of the general population, and to prevent the increase in NCDs in Japan. The NPM-DJ (1.0) categorizes dishes into staples, sides, mains, mixed dishes, and mixed dishes with staples. The model evaluates dishes based on energy, saturated fats, sugars, and sodium as restricted nutrients, while considering protein, dietary fiber, and the weight of certain food groups as recommended nutrients. The distribution of the overall score for each dish category was analyzed and a rating algorithm was created. The baseline, modification points, and final scores were significantly lower for side dishes than for staple dishes. In contrast, the baseline points and final scores were significantly higher for mixed dishes with staple. The model effectively differentiated nutritional profiles across five dishes categories, which may promote healthier dish reformulation by food businesses operators and encourage consumers to select healthier dishes.

Edible brown seaweeds, sea spaghetti (SS) and Irish wakame (IW), were incorporated at 2.5% into the formulation of reduced-fat (fat reduced from 25% to 20%, 15%, and 10%) and -salt (sodium chloride—NaCl) (salt reduced from 2% to 1.5%, 1%, and 0.5%) pork sausages. The physicochemical and sensory characteristics of the reformulated sausages were analysed. Subsequently, shelf-life evaluation (lipid oxidation and microbiological analyses) was performed on selected sausages stored under aerobic (AP), MAP70/30 (70% N₂:30% CO₂), MAP80/20 (80% O₂:20% CO₂), and vacuum (VP) conditions. Relative to the control, seaweed sausages containing 10% fat had higher (p < 0.05) protein and 1.5% salt seaweed sausages had higher (p < 0.05) ash content. The addition of seaweed did not affect the pH of reduced-fat and -salt sausages, and cook loss increased in reduced-fat sausages. Reduced-fat and -salt seaweed sausages were darker in colour than the experimental controls. Based on sensory results, the most accepted sausages using SS and IW were 10% fat, 0.5% salt (SS10f/0.5s), and 15% fat, 1% salt (IW15f/1s), respectively. With regard to the shelf life of selected seaweed sausages, MAP70/30 (70% N₂, 30% CO₂) and VP (vacuum packaging) were the most effective approaches for the lipid oxidation and TVC (total viable counts), respectively.

The reduction of sodium chloride (NaCl) content, commonly known as salt, in processed meat products is one of the objectives of health organizations and government authorities to achieve healthier products. This reformulation of traditional meat products with protected designations poses more constraints, as they have a more consolidated quality image and less margin for change, since consumers appreciate the products for their unique sensory characteristics. The aim of this work is to present some of the strategies that have been explored to obtain meat products with low sodium content. Information related to the characteristics of traditional meat products with quality marks and geographical indications in different studies is discussed in opposition to the information recorded in their product specifications. It was found that the product specifications of meat products with Portuguese Protected Designation of Origin (PDO) and Protected Geographical Indication (PGI) show a wide variation in the NaCl content, much higher than the recommended values. Thus, one of the requirements to be implemented will be the parameterization of NaCl levels and their monitorization by control and certification organizations as a way to ensure product quality. It is also urgent to examine whether healthy innovation strategies may affect the quality of traditional PDO or PGI meat products and whether they can be included in the respective product specifications.

Cardiovascular diseases account for almost 18 million deaths annually, the most of all non-communicable diseases. The reduction of dietary salt consumption is a modifiable risk factor. The WHO recommends a daily sodium intake of <2000 mg but average consumption exceeds this in many countries globally. Strategies proposed to aid effective salt reduction policy include product reformulation, front of pack labelling, behavioural change campaigns and establishing a low-sodium-supportive environment. Yet, salt for household and processed food use is, in countries wholly or partially adopting a universal salt iodisation policy, the principal vehicle for population-wide iodine fortification. With salt reduction policies in place, there is concern that iodine deficiency disorders may re-emerge. Recognising the urgency to tackle the rising prevalence of NCDs yet not risk the re-emergence and detrimental effect of inadequate iodine intakes, this review lays out the feasibility of integrating both salt reduction and salt iodine fortification strategies. Reducing the burden of health risks associated with an excessive sodium intake or inadequate iodine through population-tailored, cost-effective strategies involving salt is both feasible and achievable, and represents an opportunity to improve outcomes in public health.

Two U.S. cities require chain restaurants to label menu items that exceed 100% of the Daily Value (DV) for sodium, informing consumers and potentially prompting restaurant reformulation. To inform policy design for other localities, this study determined the percentage of the top 91 U.S. chain restaurants’ menu items that would be labeled if a warning policy were established for menu items exceeding the thresholds of 20%, 33%, 50%, 65%, and 100% of the sodium DV for adults. We obtained U.S. chain restaurants’ nutrition information from the 2019 MenuStat database and calculated the percentage of items requiring sodium warning labels across the food and beverage categories at all the restaurants and at the full- and limited-service restaurants separately. In total, 19,038 items were included in the analyses. A warning label covering items with >20%, >33%, >50%, >65%, and >100% of the sodium DV resulted in expected coverage of 42%, 30%, 20%, 13%, and 5% of menu items at all the restaurants, respectively. At each threshold, the average percentage of items labeled per restaurant was higher among the full-service restaurants than the limited-service restaurants. These results suggest that restaurant warning policies with a threshold of 100% of the sodium DV per item would cover a minority of high-sodium menu items and that lower thresholds should be considered to help U.S. consumers reduce their sodium consumption.

Sodium, sugar and saturated fat (SFA) intake in the Italian population is still higher compared to the dietary recommendations, while fiber intake is far below, especially in specific target groups. An inadequate intake of these components is associated with an increased risk of non-communicable diseases. In many developed countries, including Italy, a significant proportion of sodium, sugar and SFA in the diet comes from packaged foods added by manufacturers, while fiber content is often low also in products belonging to food groups naturally rich in fiber such as cereal-based foods. Thus, an effective strategy to reduce the intake of sodium, sugar and SFA and to increase fiber intake could be the reformulation of foods that are frequently consumed by the Italian population and therefore contribute to most of the intake of these components. Within the OnFoods project, funded under the National Recovery and Resilience Plan, the collaborative research initiative EFFORT has been developed, with the intention of investigating the impact of food reformulation on nutrient intake. The project will consist of various operational steps: (i) Identification of the main categories of products contributing to salt, SFA, sugar and fiber intake in the Italian population by considering the actual food consumption; (ii) Quantification of salt, SFA, sugar and fiber content in food products currently on the Italian market; (iii) Reformulation of food products to reduce salt, SFA and sugar content and increase fiber content; (iv) Evaluation of the potential impact of the inclusion of reformulated food products on nutrient intake in the Italian population based on actual food consumption data. The project will enable us to simulate the practical benefits in terms of diet quality achieved through the reformulation of several food categories. For instance, a first pilot study has shown that the only reformulation of shortbread biscuits may reduce the sugar intake by up to 1.65 g/day. The collaboration with food companies will be pivotal to increase the availability and analysis of data from the Italian market and to optimize the use of results in order to design accessible, affordable and acceptable new food products with implemented nutritional quality.

High sodium intake is the leading diet-related risk factor for mortality globally. Many countries have introduced policies to support the reformulation of foods and to reduce sodium intake, mainly on a voluntary basis, but there are limited data available about the long-term efficiency of such measures. Slovenia implemented salt reduction policies for the period of 2010–2020; these policies also included the voluntary reformulation of foods with the lowering of sodium content. This study’s aim was to explore the nationally representative branded food datasets collected in the years 2011, 2015, 2017, and 2020 to investigate the changes in the sodium content in prepacked branded foods. The study was conducted with datasets collected from food labels using standard food monitoring studies and included all the major retailers. Differences in market shares were adjusted by sales weighting, which was conducted using the yearly sales data provided by the major retailers. The food categories with a major contribution to the overall sales of sodium in prepacked branded foods were processed meat and derivatives (19.0%), canned vegetables (7.1%), water (6.7%), bread (7.2%), and cheese (6.3%). Considering the available food products, a notable decreasing sodium content trend was observed in biscuits, breakfast cereals, pizza, and spreads. Year-to-year differences were much less expressed after the correction for market share differences, and neutral trends were most frequently highlighted. This indicates that sodium was less frequently reduced in market-leading products. The study results revealed that very limited progress in sodium food reformulation was achieved in the 10-year period, indicating the need for more efficient policy approaches. The study demonstrated the importance of the systematic monitoring of the food supply for the evaluation of food policies. Full article
